Changes in mental health, wellbeing and personality following ayahuasca consumption: Results of a naturalistic longitudinal study.

Frontiers in pharmacology January 1, 2022 Daniel Perkins, Broc A Pagni, Jerome Sarris et al. 53 citations

Fifty-three first-time ayahuasca users (32 women, 21 men) completed questionnaires before and one month after a facilitated ceremony. Depression, anxiety, stress, alcohol and cannabis use, body dissociation, self-alienation, impulsivity, and negative affect significantly decreased, while positive mood, self-efficacy, authentic living, extraversion, agreeableness, open-mindedness, spirituality, and relationship satisfaction increased. Baseline traits—especially high negative emotionality and body dissociation, and low self-efficacy—strongly predicted improvements in mental health and substance use, whereas the intensity of the mystical experience had little predictive value. The findings suggest ayahuasca may produce broad mental health benefits and that personal traits could guide personalized treatment.

Life after Ayahuasca: A Qualitative Analysis of the Psychedelic Integration Experiences of 1630 Ayahuasca Drinkers from a Global Survey

Psychoactives June 13, 2023 Tessa Cowley‐court, Richard Chenhall, Jerome Sarris et al. 19 citations

Integrating ayahuasca experiences can be challenging and take considerable time, though working through these challenges may facilitate positive growth. A global online survey of 1630 ayahuasca drinkers (50.4% male, mean age 43) identified three main themes in integration experiences: overall appraisal (easy, challenging, or long-term/ongoing), beneficial tools (like-minded community, yoga, meditation, journaling), and challenges (feeling disconnected, returning to old life with new understandings). Findings challenge individual psychotherapy as the primary integration tool, suggesting communal and somatic elements may also be useful. An expanded definition of psychedelic integration is proposed that includes working with challenges and adjusting to life changes.
